CROSSHEAD.

Application filed December 10, 1925. Serial No. 74,644.

This invention i'elates to cross-heads used on i.'eci n'ocati.iig pumps and engines for the pn pose of guiding and stabilizing the piston rods. i

An object of the invention is to provide in a cross-head, used on reciprocz-iting pumps and engines, an improved means for packing the bearing surfaces therein against grit and foreign substances, and thus-eliminate the excessive friction and wear caused by the grit entering said cross-head and rubbing on the guide rods.

A further object of the invention isthe provision of improved means to simplify the oiling of the guidei'o'ds and thereby obtain higher efliciency, also saving much time and labor by eliminating the necessity for constantly oiling said guide rods. I

In the drawings:

Figure 1 is a central tional view of one type of cross-head involving the invention.

Figure 2 is a top plan of the invention.

According to the construction shown, the numeral 16 represents a cross-head substantially fastened to a piston rod and pivotally secured to connecting rods 14. The numeral 17 represents stationary guide rods that extend through. the cross-head and adapted to be slidable therein for the pur pose of guiding and stabilizing the piston rod.

As hereinbefore stated, the object of this invention is the providing, of improved means for packing the bearing surfaces in the cross-head and on the guide rode a grainst grit and also the provision made to allow for the proper lubrication of same.

A preferred type of such means consists of providing a cup shaped cap 19, having a hole therein through which the guide rod extends, the said cap being tightly-mounted in the cross-head 16, as illustrated in Figure 1, with the containing portion thereof facing upward, thus serving as a means for longitudinal sec holding the packing 20 in place and also providing a. container for retaining some of the lubricant used for lubricating the guide rods. The numerallS represents a liner substantially mounted in the cross-head, and may be made of bronze or babbitt or any metal that will form the proper bearing surface for said guide rods. The paehingQO is preferably made of fibrous material that is adapted to retain lubricant, and is mounted in the cross-head as illustrated, having a snug fit around the guide rods, thereby preventing grit' from coming into contact with the rubbing surfaces involved, thus eliminatingexcessive friction and wear and also providing a simple and improved means for absorb lubricant and to tit closely around said vertical rods; said packing being mounted in the cross-head above and below said bearing liners: a plurality of cup shaped caps mounted. in the cross-head and adapted to hold the packing in position therein; said cup shaped caps facing upwardly when the crosshead is in its working position on the vertical rods, substantially as described.

In testimony whereof, we hereunto a. our signatures.
